disassembly to [MnL] and [MnL2 ] followed by ligand modification before reassembly to Mn4 L'6 via [MnL'], [MnL'2 ], and [Mn2 L'3 ] with increasing solvothermal temperature up to 140 °C. Identification of intermediates [Mn4 Lx L'6-x ] (x=5, 4, 3, 2, 1) in the process further suggested an assembly/disassembly/in situ reaction/reassembly transformation mechanism. These results not only reveal that multiple phase

L2·5 H2 O·5 OH(Mn4 L4)和[MnII 4(H2 L')6(μ3-OH)] Cl·4 OH·H2 O(Mn4 L'6)。它们的结构通过单晶XRD确定。对反应溶液和固体进行广泛的ESI-MS研究得出了这样的建议:首先在80°C以下通过[MnL]和[Mn2
L2]从反应物中逐步分步组装Mn4 L4,然后分解为[MnL]和[Mn
